Changed the oil, check oil pump and chain...
Been due a while and figured today is a good day to do it. Been putting it off because I wanted to pull the pan and check the pump bolts and chain. The chain wasn't real loose, surprised me actually. All the pump bolts except 3 were loose, those were in the oil pan. Tightened it all up and put in the new oil (0w-40 Import Mobil 1). Motor is real quiet now, will reboot the computer tomorrow after I get it warm to see if anything is different or better.
Funny thing is the lifters on the right side used to always chatter until I changed the valve cover gaskets then they went quiet. No clue what that was about. Anyways good for another 9K.
